PROBLEM TO BE SOLVED: To provide a radiation monitor capable of easily and reliably preventing an external noise from being mixed.SOLUTION: The radiation monitor 10 includes a radiation detector 11 including a radiation detection part capable of detecting radiation and a dummy radiation detector 12 comprising the same structure as the detector except the radiation detection part and incapable of detecting radiation. The radiation monitor 10 receives a detector signal transmitted by the radiation detector 11 and a dummy detector signal transmitted by the dummy radiation detector 12, determines whether or not the dummy detector signal is received concurrently with the detector signal when the detector signal is received, and outputs the detector signal when the concurrency is not determined. When the concurrency is determined, the radiation monitor 10 determines that the detector signal is a noise, and does not output the detector signal to an output part 132. |
